Planets & Asteroids - cover render of every body in the pack

5 planets, 8 asteroids, a moon and a star as clean solo bodies, ready to drop into a space scene. Planets: two banded gas giants, an ocean world with mountain chains and polar ice, a fractured ice world, and a volcanic world with emissive lava channels - 65k tris each, 2K PBR, seamless equirectangular maps with no baked-in lighting, so they light correctly under your own sun. Moon: an airless cratered world in cool greys, built like the planets but with far deeper relief. Star: a yellow-white main-sequence G-type - emissive, so its colour is its own light; drop it in as a sky sun or a distant light source. Asteroids: 8 distinct rocks (~31-53k tris) with 7 material presets each - ironstone, earthlike, nickel iron, glacier ice, cinder iron, rust oxide and copper ore. The presets are texture sets that share one mesh and one normal map, so you import a rock once and swap materials without re-importing. ENGINE SUPPORT, TESTED: every model ships as.glb (full PBR) and.fbx (same geometry, round-trip verified). Unreal Engine 5 imports the.glb natively with no plugin - verified triangle-for-triangle on 5.8.2. Unity has no built-in glTF support, so use the free glTFast package with the.glb (verified on Unity 6: full mesh, material and all maps), or use the.fbx with no install and assign the included loose texture maps yourself. The pack README spells out both routes. No ring or debris belt is welded into any planet or the moon: each body is a single closed watertight shell, so you build the belt yourself from the asteroids and keep control of orbit, density and scale. Y-up. Every model tested and its SHA-256 published in the pack (15/15 PASS) - planets, moon, asteroids and star get different gates, because a world, a rock and a star fail in different ways. If you bought v1, this update is free. AI-assisted: the planets, moon and star are computed numerically, not AI-generated; the asteroid base meshes came from AI concept art through image-to-3D and were closed, verified and materialled by us.

15/15 models passed our solid-body mesh check, each bound to the sha-256 of the file you download · card previews are renders of those same shipped models · an internal check, not a third-party certification.

The items

Drag any card to turn that body in your browser. The mesh is the one you download, with its textures reduced to 1K for the web - the archive carries the full set. Until a card's mesh loads it shows a render of that same file. These are static models: no rig, no animation, nothing to play.

What is not included - measured from the archive: meshes per item: 1; materials per item: 1; embedded images per GLB: 1/3/4; no animations or skins in the shipped GLBs (static props).

Not provided, by design: no LOD chain; no separate high-poly source archive; no collision meshes; no destructible or animated variants; meshes are AI-generated (TRELLIS) as baked, not hand-modelled. Canopies are painted or smoked albedo, not glass.

What we certified

Every check below ran on the exact files you receive - each result is bound to the sha-256 of that model inside this download. 15 of 15 models passed.

Equirectangular world certification · 6 models

W1File loads completely - the file opens in any glTF importer without errors6 of 6 pass
W2Textures are inside the file - nothing goes pink or grey because a texture is missing6 of 6 pass
W3Full PBR material - the surface lights and shades correctly instead of reading as a painted ball6 of 6 pass
W4Equirectangular maps (2:1) - the texture wraps a sphere the standard way, so you can swap in your own map6 of 6 pass
W5Closed sphere - no gaps at the poles or along the seam6 of 6 pass
W6One hollow shell - a planet is a surface, not a solid lump - one shell is correct, two is a defect6 of 6 pass
W7Relief inside the declared envelope - the terrain is exaggerated on purpose so it reads at game distance; this is the number, so you can judge it rather than guess6 of 6 pass
W8Faces wound consistently - no faces render inside-out when backface culling is on6 of 6 pass
W9UVs inside the texture - your own equirectangular map will line up without editing6 of 6 pass

Solid body certification · 8 models

S1File loads completely - the file opens in any glTF importer without errors8 of 8 pass
S2Textures are inside the file - nothing goes pink or grey because a texture is missing8 of 8 pass
S3Full PBR material - it lights correctly in a modern engine instead of looking flat8 of 8 pass
S4Surface is closed - no holes - you cannot see through the rock, and it will not leak in a physics or boolean step8 of 8 pass
S5Manifold - no pinched edges - booleans, simulation and 3D printing all work on it8 of 8 pass
S6One solid body - it is a single rock, not loose fragments that can drift apart8 of 8 pass
S7Faces wound consistently - no faces render inside-out when backface culling is on8 of 8 pass
S8UVs inside the texture - textures do not wrap around and repeat where they should not8 of 8 pass

Star body certification · 1 model

ST1File loads completely - the file opens in any glTF importer without errorspass
ST2Texture is inside the file - nothing goes pink or grey because a texture is missingpass
ST3Emissive surface - the star is its own light - a star glows by design; its colour IS its light, so it reads correctly with no lamp on itpass

ST5Closed sphere - no gaps at the poles or along the seampass
ST6One hollow shell - a star is a surface, not a solid lump - one shell is correctpass
ST7No baked lighting, no false relief - the look lives entirely in the emission map, so it lights your scene rather than being litpass
